The 20-year-old has started to make a name for himself on the ATP circuit having won four Tour events including the Citi Open last weekend.
Zverev's reputation has grown massively over the 2017 campaign and he is being touted as a future Grand Slam champion following some impressive performances.
The German insists he is delighted with the way the season has unfolded and hopes to continue on the same track in the final few months.
Zverev said: "I'm happy where I am.
"But the season doesn't stop now. It's only August. There's still a lot more tennis ahead of us, and we'll see where I can be at the end of the season."
